In early 1985, Michael J. Fox's days were already dedicated to taping the hit sitcom Family Ties, but then the chance of a lifetime came his way. Soon, he committed his nights to a new time-travel adventure film being produced by Steven Spielberg -- Back to the Future. Fox's nightly commute from a soundstage at Paramount to the back lot at Universal Studios, from one dream job to another, would become his own space-time continuum. In Future Boy, Fox tells the remarkable story of playing two landmark roles at the same time -- a slice of entertainment history that's never been told.
